THERMOSTAT

Abstract: Air thermostat suitable to use on different heating-stoves which is also usable to ventilation. The one register-third-part is regulated manual, another thermostatic. The register has minimum holes which even when the register is closed let air flow toward the temperature-sensor. A conducted combustion saves energy and provides a sturdy room temperature. There are different types.

Description: Thermostat 1# System to thermostat regulating for instance heating-stoves or the like, or to thermostat regulate ventilation. As different from known German pat. 683 492 el 24 gr 2 where the claim describe function as only 'partly' depending on room-temperature, this system is aimed on and able to regulate only according to room-temperature. As different from German pat. 270 796 el 24 gr 2 this system is aimed on and able to react on room-temperature without remote sensor and even if it is amounted on a hot heating-stove surface. The system is different from some known devises built in to or only matching a specific heating-stove as said system can be amounted on an will work on any heating-stove. It must be understood that non of the existing patents describe a thermostat which, without remote sensor, are aimed on, and can, regulate a heating-stove only according to room temperature. 2# The normal air-regulator (control) is a disk with a thread-hole which can rotate on a bolt which is mounted in the middle of the combustion-air inlet-hole, or similar method whereby the opening can be variable. Known is a thermostatic conduction build in to, or on, a heating-stove, by different means and on different places, which sense the temperature of the heating-stove and a little of the surroundings. Different devises is known to regulate a Heating-stove but they are depending on remote sensor and or control. It is known with a device to amount on a heating-stove which regulate the airflow partly in relation to the surroundings temperature, the device is a different construction, design and function. A example is Germany patent: nr. 683 492 cl 24i gr 2, origin franee. Germany pat. 21717 cl 24 gr 2 describe a temperature- regulator with 3 register-disks, where one is for maximum-regulating, it can not work when amounted on a hot surface as there is no airflow around the temperature-sensor, this particular with slow flow where it will sense a temperature between the flowing air and the surroundings. 3# The Thermostat regulate as example heating-stoves or the like, or ventilation. The thermostat regulate a airflow according to the incoming airs temperature and have a adjustable minimum airflow such that a heating-stove dos not extinguish when the thermostat close do to enough temperature and a minimum smoke-temperature in chimney can be kept. The hole minimum airflow flows through the minimum register and through and or around the temperature sensor, moreover the main air flow around the SUBSTITUTE SHEET temperature sensor which will be cooled approximately in relation to the energy emitted from the heating-stove, whereby is obtained very accurate regulating according to room-temperature, not disturbed by the heating- stove. The air thermostat in connection with the combustion air intake on a heating-stove, which are heating the rooms in which it is placed, will work on many different heating-stoves and replace a manual regulation on used, old or new heating-stoves. The Thermostat is much smaller and compact and easier to regulate than the known and does consist of few parts. The thermostat can regulate ventilation in relation to the temperature in a room, example; greenhouse laboratory growing of germs or plants, possible in connection with remote control. 4# System where the Thermostat regulate a air flow only according to the incoming airs temperature and have a manually adjustable Minimum- register. The hole minimum air flow is through the Minimum-register and through and or around the Temperature-sensor, maybe conducted by a nozzle, and around a heat-shade and the surrounding structure, moreover does the main airflow flow around the Temperature-sensor and heat-shade and structure which all will have nearly same temperature as incoming air, as the emitted heat from the said heating-stove is in relation to the hole incoming airflow. The said Temperature-sensor have direct connection with the regulating Register. Said system with additional system able to open and close said Register in the thermostat according to the temperature of heating-stove. The front-part, hereafter mentioned as 'Lid' , can cover both front and sides of the sturdy back-part here after mentioned as 'Base'. Said Base can be round with a Lid which fit to and can turn on the outside for adjustment of temperature. Said Base can be squared (drw. 1,3) or any other form where a likely formed said Lid and all the other mentioned moving parts moves linear, that be vertical or horizontal or any thing there between, the connection air-holes in the 3 registers can have a angel between different moving-directions such that registers moving in different directions work according to said systems. The Thermostat can be in connection with the combustion air intake on a said heating-stove, which can heat the rooms where it is placed, or by other means have connection to. There is a Insolating layer for instant ceramic wool between said Thermostat and said heating-stove. The said heating-stove can burn wood, coal or any other solid material. The air- Thermostat means that it easy can be fitted to and will work on most heating-stoves, means it can replace a manual operated regulation on a normal used/old or new heating-stove, converting heating-stove to be conducted by the room temperature.
